To all whom it may concern:

Be it known that we, Josue H. DIGKIN- son, a citizen of the United States, and a resident of Montclair in the count of Essex and State of New Jersey and BRIAN H DIOKINSON a citizen of the United States, and a resident ofSeattle, in the county of King and State oiWashington, have invented certain new and usefulIm rovements in Loggin Apparatus, of which t e following is a s cc cation.

his invention enables a lo to be skidded from a distant point and dec ed at one side of a railroad track by a single automatic operation and a sin 10 skidder line actuated from the platform 0 a car.

Hitherto, in portable skidders with which we are acquainted, it has been customary to locate the lead blocks in a position approximately above the track upon which the op paratus moves, so that it was necessary to pull the logs out approximately at right angles to the suppprts for said h ocks, such as the loading or s idding boom carrying the blocks. To such construction certain disadvantages are incident. For example, the rope running from the engine on the platform had to pass over the lead block in a position approximately above and parallel to the tree and then in engaging the log ofl the track, it is necessary for therope to bend sharply at right angles. Th's usually results in wearing out the side of the sheave block rapidly, in sawin or wearin the ro e, and also results in placing an a normal strain upon the pin of the sheave block. Furthermore, in such a construction it is im ossible to properly pile the logs without emp oyin a decking rope; and a decking crew, especia ly when large quantities of logs are to be pile That is to say, when the skidding boom projected above and approximately parallel with the track and the ropes led off at an angle to such boom, the logs could not be piled or decked for the following reason: Should several logs be drawn in h the skidding line he track, logs subsequently hauled in could not be elevated or lifted at one end before they reached the osition of the previously drawn in logs, wit the result that the forward end of the incomin logs would nose. or strike, against those a ready at the machine. Consequently, to pile or deck the logs, it 'is necessary to arm ploy an additional line commonly termed the at the track which is used to engage the logs and pile or deck the same, that is, bringing the logs around parallel to the track.

A further disadvantage in the'maehines of the type referred to ls that as the skidding lines extend at approximately right angles to the boom, it is necessary to guy the opposite side of the boom and resist the straw or ulfll resulting from the skidding line and its 0a In the present invention it is our purpose to provide a skidding machine whereby the decking line,

logs may be piled or decked adjacent to the machine without the necessity of rehandling the log, after it has been skidded, by a decking line or otherwise.

A further advantage incident to our construction is that the pull or lead of the skiddin line is always approximately straight, or irect over the sheave block, instead of at a great angle, with the result that the wear upon the sid s of the block is avoided, the

strain upon the pin of the block relieved and the rapid wearing or sawing of the skidding ro e reduced to a minimum.

till another advantage incident to our invention is that it is unnecessary to em loy guy ropes to resist the opposing pull 0 the skidding line.

With these and other objects of a like nature in view, the invention consists in the construction, combination and arran ement of parts set forth in and falling wit in the sco e of the appended claims.

n the accompanying drawings, Figure 1 is a view in elevation of our improved apparatus, such view illustrating a portab e skldder in position for log ing. In th s case the platform carried by t e traction devloe is swiveled, and is shown as turned at approximately right angles to the car. Fig. 2 1s a side View '0 the transporting vehicle, and also showing the latform turned into the same position as s own in Fig. 1; Fig. 3 1s a view showin the platform turned approximately ara e1 with the track and in cs1- tion to e transported from place to p ace; Fig. 4 is a plan view showing a drivin mechamsm for making the car self-prope mg, so arranged that the apparatus may be propelled irrespective ofthe p0 Bli'1lOI1 of the platform upon the can; Fig. 5 s a view of a modified form oi apparatus, in this instance, the platform remaining normally stationary elativc to the transporting cars, and having mounted thereon skidding aplparatus adapted to haul the logs transverse y of the track; Fig. 6 is a top plan View of the construction shown in Fig. 5.

ltcferring now to the accompanying draw ings in detail, and especially to Pigs. l. to '1- inclusive, A designates a vehicle or transporting car of an r suitable improved charac ter, having revolubly mounted thereon the platform or base B. (I and D designate en gines mounted upon the base, and when the apparatus is to be made self-propelling, one o the engines, for instance, the engine D, may be used to drive the transporting truck or car. One method of accomplishing this is shown in the drawings, wherein 5 is a beveled car driven in any manner from the engine as shown in Fig. 2, as, by a shaft 5" upon which the said gear 's mounted, said shaft having fixed thereo-i a beveled gear 5", which in turn meshes with a beveled gear 5", the latter being driven in any suitable manner from a rotatin part of the engine or its ap urtenances. T 1e gear 5 meshes with a similar bevel 6 carried by the shaft 7, such shaft at its opposite end carrying a gear 8 intermeshing with gear 9 carried by the vertical shaft 10 which meets through the platform of the car, w iici shaft also acts as a king-pin or swivel for the derrick platform, whereby the latter may be turned in the manner of a turntableupon thei car. The lower end of the pin 10 carries the gear 11 meshin with the gears l2, 12 carried by the incline shafts 13, 13, the latter in turn carryin gearing 14 meshing with the gears 15 on t 1e axles of the 'car trucks. By such an arrangement it will be readily observed that power may be transmitted from the engine to the trucks to propel the apparatus as desired. When the latform is turned aproximately transverse y to the car and tree and it is desired to maintain the saine in position, as shown in Fig. l, we may rovide suitable jacking mechanism or stan ards, 16, which act as supports and give rigidity to the apparatus and maintain the latter in stationariy position. We may employ any suit'ab e number ofthese sup orts 16, four boing-gen orally considered su cient. Mounted upon the platform B are the vertical uprights or masts 17, of any suitable character, said masts being tmssed or braced by the truss rods 18, 18. Preferably pivoted adjacent to the foot of each mast is a skidding boom 19, carrying" the lead blocks 20, over which pass the skidding lines 21 carrying suitable og-engagin devices such as tongs 22. These- BklCl ing lines are operated from the drumsc, c, and d, d, of the engines. Each boom referably al o carries the pulley 23 and t e masts l7 carry pulleys 24, an through the pulleyof the boom and the pulieys o the mast is reeved the rope 25, having or supporting logs are then lowered to pull.

decked in the direction hey are skidded one end passing down to and operated by the adjacent engine, the above arrangement forming a block and fall, being employed to raise and lower the boom relative to the mast. This block and fall arrangement l)l.. tween the mast and the boom presents certain advantages. For instance, the pulling or skidding booms may be raised to approxi mately a vertical position adjacent to the mast and the machirw thereby narrowed during the transportation, csiecially when it is only desired to move tie machine a short distance and thereby render it unnecessary to turn the platform from its position transversely of the carrying vehicle to a position approximately longitudinally thereof.

From the above description the construction and operation of the a paratus as shown in Figs. 1-4- inclusive will Le readily apparent to those skilled in the art. Presuming the machine to be traversing the track to the point of use, the platform is generally turned into the position shown in Fig. 3; that is to say, longitudinall of and parallel with the car platform. hen the machine has reached the point of use the platform istnrned upon its pivot, or swung to the position shown in Fig. 1, that is, so that such platform extends approximately transversely of the track and the jack screws ve rigidity and stability to the structure. he skiddingllinesare then drawn out in the usual manner, for connection with the logs and in this osition, as shown i'n Fig. 1, it will be note that not only do the skidding ropes take a direct lead over the skidding blocks at approximately right angles tothe track, but a direct lead is also had off the engine drums. By this arrangement the logs may be hauled in to a position adjacent to the machine. As a log approaches the machine the tendency will be for the forward .endcf the log to rise when it is a short distance from the machine and in front of the skiddin boom, due to the direction of the his enables the lo s to be piled or of a turntable upon the car body. In these Figs. 5 and 6 we mount a center n ast2 6' preferably in the nature of an A frame suitably supported, as'by the stay rods 27; The skidding booms 28 are also preferably of an A-frame form and pivoted as at 29, although it will be understood that these booms'inay apparatus shown in l igs. '5 and 6.

2pc of further object of construction shown in Figs. 5 and 6 is that we are enabled to employ a relatively narrow base and. therci; obviate the employment of supporting jae {S or legs and may also dispense with the employment of guys, as in this construction we .rint, the center of gravity of the machine well over the trucks. In skidding o erations, espe ciall where strictly portab e machines are elnp eyed, it is always desirable to skid the logs directly at right'angles to the track and directly posite to the machine, rather than to make t he longer Pulls caused by skidding in every'direction rem the mac line. For instance, if a log be lying 80.0 feet distant from the machine, to one side and forward thereof, but only 200 feet from the track in a direct line, it is referable to trans ort the machine to a pos ,tion a -proz u'rnate,y o poit he log and mak -i pull o 20.0 eat, han to make th longer pu l of 800 feet.
